I wanted to trim down the size of a program (~12K compiled) by eliminating calls to printf and puts and using their ARP equivalents. I found I could save 2K by doing this is a "hello world" program that used printf, but there wasn't any real savings when I changed my larger program over. My question: do other Aztec C functions contain calls to them hidden away? If so is there a way around that limitation? The DOS calls that are still used in the program are fopen, fread, fseek, fclose. All references to printf, puts, and fprintf have been replaced by ARP equivalents. John

Sure.. don't call library functions Manx'ish.. or get the source to the libraries and change 'em. -- Pat White ARPA/UUCP: k.cc.purdue.edu!ain BITNET: PATWHITE@PURCCVM PHONE: (317) 743-8421 U.S. Mail: 320 Brown St. apt. 406, West Lafayette, IN 47906

I've looked at *all* of the Aztec C calls, and I don't believe I remember a single one with printf()'s in th. puts() yes, printf() no. One minor thing---(3.4b, anyway)---setenv by itself increases the size of your executable by 2372 bytes. main() { getenv(); setenv(); } weighs in at 4700 bytes; main() { getenv(); } weighs in at 2328 bytes. Not too surprising, as there has to be a copy of the environment library structure in there somewhere, but I think that still may be a bit larger than it could have been. -tom

Hi!
With Manx I found the most sizesaving feature to use Open, Write
instead of fopen, fwrite. (Amigafunctions vs. Un*x).
Should save you about 6K.
